5 Claims.

This invention relates to printing or embossing machines, in which pensor articles to be embossed or printed are held in position to enable atypewheel to be selectively operated, and pressed against the article tobe embossed.

This invention consists more particularly in the means of holding thearticle, said means being of simple construction, and readily operable,so as to firmly hold the article when operated upon, and permit itsready insertion and removal. For this purpose pivoted jaws are providedwhich, when open, permit the ready insertion of the article, and whenclosed securely hold the article and hook it in position, the jaws beinglocked in position, while the article is being operated upon. Thisco-relationship of parts is set in an environment so as to enable thearticle while thus held in position, to be moved step by step, to enablethe letters or numbers to be printed, to be successively appliedthereto.

The invention will be further described hereinafter in connection withthe embodiments thereof shown in the drawings, and will be finallypointed out in the claims.

.5,. heated by means of the conductors 2|, serves in a manner well knownto heat the type II. A

spring 22, secured at one end 23 at 24, and exerting its force throughits other end 25, against a shoulder 26 of the casing l3, serves to movethe casing |3 to its initial or normal position after it has been movedto its operative position by the handle M. The type H of the type wheelI6 is visible through an opening 21 of the casing, and the selected typeprotrudes through the casing |3 at 28, the type IT moving in thedirection of the arched arrow 29 when the casing is moved downwardly bythe handle l4. The type to be used is selected by the rotation of handwheel i9. No novelty is claimed in any of these parts.

The article 33 to be pressed, stamped, printed or embossed, is held byjaws 3|, so as to expose the surface of the article to be operated uponas clearly shown in Figure 1, when the selected type comes down in thepath of the arched arrow 29.

These jaws 3| are supported on a carriage 32 having extensions 33,entering guide ways 34 of the casing I0. The jaws 3| are opened orclosed by the drawing up of a spindle 35 within a sleeve 50, by means ofa handle 36.

At the ends of the jaws 3|, there are provided clippers 38, which serveto hold a piece of gold paper or the like, upon the jaws 3|, and overthe article to be operated upon.

The carriage 32 is moved longitudinally in its guide ways 34, step bystep by a mechanism now generally referred to as 40, which mechanism isset in operation with each downward movement of the casing |3, so as toenable the next selected type to consecutively follow and aline with andto be disposed alongside the previously printed character.

Referring now to Figures 5 and 6, the jaws 3| are provided with a seatportion 4|, and an enclosing portion 42. Each jaw at its lower portionis pivoted at 43 to the carriage 32, by virtue of which the jaws areloosely supported, and are freely movable in respect to each other.

The jaws 3| are provided with openings 44 through which passes thespindle 35, which at one end is provided with an enlargement 45 having acurved surface 46 engaging a corresponding bore portion 4'! in one ofthe jaws 3|. As seen in Fig. 5, the openings or bores 44 are slightlylarger in diameter than the diameter of the spindle, whereby a certainlost motion between the parts exists. A similar enlargement 41 with acurved surface 48 engages a corresponding bore portion 49 in the otherjaw 3|. The spindle 35 extends beyond this second enlargement and passesthrough a sleeve 50. To the free end of the spindle is secured thehandle 36. By the turning of the handle 35, the jaws 3i are eitherbrought together as shown in Figure l, or away from each other as shownin Figure 5. At the enlargement i5, there is provided a pin 5i thereon,which enters an opening 52 of the jaw 3| to prevent the spindle or bolt35 from turning. The action of the spindle 35 overcomes the action ofhelical spring 5% seated at its ends in recesses 55 of the jaws 3i,which spring has a tendency to keep the jaws open.

In Figure 6 is also shown the gold leaf holding clippers 38, which arepivoted to screws 58 (shown in Figure 1), and have in addition to theparts already described, extending portions 5?, which are shaped to beable to be conveniently manipulated by hands of the operator, and areforced outwardly by the springs 58 having one end seated in recesses 59and the other ends pressing against the extensions. The result of theaction is that the free ends 68 of these clippers 38 hold the desiredgold paper of the like against the top surface of the jaws.

Referring now to Figures 1, 2 and 7, there is secured to the lower endof the casing [3, a lever arm 52 to which is pivoted a lever 53,(heretofore generally referred to by the mechanism (it, in Figure 1),and to this lever 63 is secured a spring 66, having its other endfastened to the extension E5 of the housing 13. The lever 63 is bent soas to present a longitudinal portion 66 to a plate 67, having an upwardextension 68 passing through the portion 36, and a pin 55* passesthrough the extension 63, so as to connect these parts together. Theplate 61 is pivoted to the base ill by the pivot l6 (see Figure '7). Theplate 6? has two elongated openings ll, through which pass uprights 1'2of rods 73, suitably guided on the base ii]. These rods have sharpenedpawl-like ends M which engage a ratchet or rack 15 forming part of thecarriage 32. Only one of these pawls it engages the rack E5 at one time.The plate 87! is acted upon by a spring it passing around the pivot post70, which spring has its free ends 'i'l engaging the uprights 12. Thecarriage 32 is provided with a downward extension E8, to which isattached one end of a spring 79, having its other end secured to thebase Hi, as shown in Figure 4. By this mechanism generally referred toby the character it, the carriage 32 is moved step by step, with everydownward movement of the handle i l. The lever 63 moves the plate Bl andthe rocking movement thereof causes one or the other part 13 to engagethe rack 75, and by this escapement action the carriage 32 and the jaws3| holding the pen or the like, are moved so as to be in position toreceive the next type action. After this printing operation has beencompleted, the carriage can be moved back to its initial position, so asto remove the pen or the like, and a new one can be inserted, and theoperation repeated.

The carriage 32 abuts in one position of its movement against a stop 32shown in Figure 4. It is detchably fastened to the plate 33 by means ofa pin 9! supported by the carriage 32 and this pin 9! engages a recess92 of the plate 33. The pin 9| extends upwardly to handle 86, suitablygripped by a screw-threaded thumb button 89 adjustable against a springplate 88 secured at 85 to the carriage. A spring St is interposedbetween an enlargement 99 of the pin 9! and a shoulder 35 of thecarriage, which spring Siil serves to press the pin 9i downwardly intothe recess 92. The carriage 32 is movable along the extension slide 95.When the carriage is so moved outwardly on the extension 94, and thenreturned to the position shown in Figure 4, the protruding pin 9| willfirst strike the beveled portion 93 of the plate 33, and ride on thesame until it comes over the recess 92, and drop therein and thusinterlock the carriage 32 and plate 33. In order to move the carriage 32outwardly on the extension 94, it is first necessary to lift the pin 9!out of its recess 92 by raising the thumb-nut 89 upwardly.

In Figure 5, the limit of the swinging movement of the left-hand jaw isindicated by the lines passing through the pivot 43, and referred to bythe phrase limits of swinging.

The electric heater 8!] is arranged so as to be close to the type wheelIS, in order readily to heat the type II, as shown in Figure 1 andFigure 8. The thermostat 20 is placed against the type wheel It. Thethermostat is arranged in a housing Bl to receive a spring-pressed blockhaving a bore in which the thermostat 20 is located. The springs areindicated by 82.

In order to prevent the type I! from pressing into the body of thearticle to be stamped, a safety guard is provided. This consists of apivoted lever 83 which has a pivot rod 84, held on an adjustable support87 having a rod 95 slidable in the type wheel casing H. A screw 96acting upon the rod 95 fixes the rod tightly in the desired position. Aspring 91 presses the guard or lever 83 downwardly as shown in Fig. 8.The guard 83 extends to the type wheel l6, over a shoulder 98 of thetype wheel and proximate to the side of the type. When the stampingtakes place the guard is pressed against the article to be stamped andthe guard is then pressed by the article against the shoulder 98, andthereby the entrance of the type I! into the article itself is limitedin extent.

The improved device is very simple, in that it is only necessary to openthe jaws to receive the article to be operated upon, and when thearticle has been placed between the jaws, to close the jaws, and therebysecurely hold the article, during the stamping operation.

My invention has been illustrated and described with some degree ofparticularity, but it is understood that changes may be made in the formof details and in the construction and arrangement of parts withoutdeparting from the spirit and scope of the invention or the scope of theappended claims.
